304 Stainless Steel Seamless Pipe

304 Stainless Steel Seamless Pipe

304 stainless steel is a widely used chrome-nickel stainless steel. As a widely used steel, it has good corrosion resistance, good heat resistance and low temperature strength, easy to press, bend and other hot processing, non-hardening heat treatment (temperature is -196 ° C to 800 ° C), in the...


304 Stainless Steel Seamless Pipe is a steel pipe that is resistant to weak corrosive media such as air, steam and water and chemically etched media such as acid, alkali and salt. Its corrosion resistance depends on the alloying elements contained in the steel. Chromium is the basic element for obtaining corrosion resistance of stainless steel. When the chromium content in steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface. It can prevent further corrosion of the steel matrix. In addition to chromium, the alloy elements commonly used in stainless steel seamless tubes are nickel, molybdenum, titanium, tantalum, copper, nitrogen, etc., to meet the requirements of stainless steel structure and performance for various purposes.
